The 133 MHz clock rate is the practical ceiling for this part's SPI bus. In Quad I/O mode, a single read command can transfer four bits per clock cycle, so the effective throughput is well above what a standard single-bit SPI at the same frequency can manage. That matters when the host MCU or FPGA needs to execute code-in-place or stream large lookup tables without wait states. The flash wait-state count must be set correctly in the memory controller for 133 MHz operation — at lower frequencies the margin relaxes, but the full speed requires the controller to support the Quad I/O protocol natively. ## Industrial temperature range — deployment envelope The 8-WSON package's exposed pad helps pull heat from the die to the PCB copper plane, which matters when the part is running sustained read bursts at 133 MHz in a warm enclosure. The storage temperature range exceeds the operating range, but the operating limit governs the system's ambient spec. The FL-S series is a mature, widely deployed NOR Flash family, and Cypress (now Infineon) continues to support it. ROHS3 compliant. No official successor has been published because the part is not being phased out.","metaTitle":"S25FL128SAGNFI000 128Mbit NOR Flash, Quad SPI, 133 MHz","metaDescription":"Cypress S25FL128SAGNFI000 128Mbit FL-S NOR Flash with Quad SPI interface, 133 MHz clock, 2.7-3.6V supply, -40 to 85°C.","metaKeywords":null},"attributes":{"series":"FL-S","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"FL-S","Package":"Tray","Technology":"FLASH - NOR","Memory Size":"128Mbit","Memory Type":"Non-Volatile","Memory Format":"FLASH","Mounting Type":"Surface Mount","Package / Case":"8-WDFN Exposed Pad","Product Status":"Active","Clock Frequency":"133 MHz","lifecycle_stage":"eol_hot","Memory Interface":"SPI - Quad I/O","Voltage - Supply":"2.7V ~ 3.6V","Base Product Number":"S25FL128","Memory Organization":"16M x 8","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-WSON (6x8)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.4900","priceTiers":[{"qty":1,"price":"$4.49000","currency":"USD"},{"qty":10,"price":"$4.07100","currency":"USD"},{"qty":25,"price":"$3.98320","currency":"USD"},{"qty":40,"price":"$3.96150","currency":"USD"},{"qty":80,"price":"$3.55200","currency":"USD"},{"qty":338,"price":"$3.53908","currency":"USD"},{"qty":676,"price":"$3.40975","currency":"USD"},{"qty":1014,"price":"$3.24163","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/S25FL128SAGNFI000/alternatives.json"},"ai":{"faq":[{"question":"Can S25FL128SAGNFI000 be used with a 3.3V supply?","answer":"Yes."},{"question":"What is the equivalent of S25FL128SAGNFI000?","answer":"For a drop-in footprint match at industrial temperature, the S25FL128SAGNFI000 is the WSON variant; the SOIC version requires a board layout change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/S25FL128SAGNFI000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/S25FL128SAGNFI000 when reusing this data.
